I have a 260 and have always thought that the wiper motor is underpowered, not just compared to new cars, but even to something as old as a 79. I have never heard anyone alse complain about this, however. The alternator is new, can't vouch for the wiring though. I need to know because,as many of you are probably aware,a new motor runs almost $400 and I would feel pretty stupid if I spent money on one and it didn't improve the situation. Any thoughts would be appreciated.
